| Re: Internal balance cranks Eagle does make an internally balanced crank for SBF applications.
There's one going into my 331. No Mallory metal required - just clean-up balancing for the Bob-Weights that should be in the +/- 5 gram area..
Yes the internally balanced engines do seem to run out better and as most know the Small Block Ford (302 in particular) has had a checkered history with block/main failures. Obviously there are some good alternative aftermarket blocks that will help in this regard.
The only caveat I would have is that there are fewer flywheel / balancer combinations available for the Internally Balanced configurations. Virtually NO balancer available for the short serpentine balancer made for the later Ford Explorer and Mustangs.. |
